Specs per Rockford Fosgate:

POWER RATINGS:

-4 Ohms - 15 watts per channel continuous power, both channels driven into 4 Ohms from 20-20,000Hz with less than 0.05% THD

-4 Ohms - 30 watts per channel continuous power, both channels driven into 4 Ohms at 1000Hz with less than 10% THD

-2 Ohms - 30 watts per channel continuous power, both channels driven into 2 Ohms from 20-20,000Hz with less than 0.1% THD

Frequency Response - 20-20,000 Hz +/- 1dB

Bandwidth - 15 - 100,000 Hz +/- 3dB

Damping Factor:
At Circuit Board - over 200 (at 4 Ohms)
At Speaker Lead - over 50 (at 4 Ohms)

Signal to Noise Ratio - Over 80dB unweighted

PROTECTION:

The Punch 30HD Mosfet is protected by two 3-Amp speaker inline fuses and by a 7-Amp battery fuse. A thermal switch shuts down the amplifier in case of overheating. Internal circuitry limits power in case of overload.

DIMENSIONS:

6.1" Long x 7.1" Wide x 1.6" High


I posted a video review of the amp, showing the amp itself and connections. I will post another video soon reviewing the sound quality and power output. If anyone has a "verification sheet" from a Punch 30HD, please let me know the actual power output.

That's cool...can you verify the power connector on my 30HD? Other pictures I've seen online have the speaker outputs coming out where the power connection is on my amp. I'm planning on using this amp to build an "old school boombox". I'm still working on the design and components, but it should be pretty sweet. I'm still not sure the P30HD is "beefy" enough and may use a P45HD instead.

I have the same connector as that. I know the older punch series had the direct wires for power and speaker outputs. I just sold a 45hd earlier this year also lol, very underrated amps!

Thanks for the info. I also have a P45HD I originally purchased back in 1992. I sold it to a friend about 10 years ago and just got it back a few years ago, only missing the verification sheet and an older P150 1st gen amp shroud (by Perfect Interface). I have one more of those shrouds somewhere, just can't put my hands on it...

My P45's verification sheet stated 91 watts/channel into 2 ohms! Not much by today's standards, but impressive for an amp rated at 45 watts total!

I'm sure someone out there has a verification sheet for a Punch 30HD?
